Nvidia 7800 GS OC - System Restarting (Help)

[d1rekt]

I downloaded the F.E.A.R demo and it will let me play it some of the way through but it always ends up with the screen going black and the PC restarting. I just installed this 7800 GS OC from BFG the night before last. Any solutions? I know it cant be heat because I have purchased a 4800RPM fan that really circulates the air. I felt it when the PC restarted and the air was of room temp. not even warm. Same for the new Power Supply.

Question: How do I keep my PC from restarting while playing FEAR?

Question: Could it be the game?

Thanks in advance!

I think it may be your PSU

My guest would be the PSU as well, heard the Rosewills didnt have good rails at all.

Is this happening in any other game?

Nope just the F.E.A.R demo. I'm playing Counter-Strike Source and HL2 at highest settings fine.

had a similar problem as you, with my 6800gs, with fear demo to, got the full version it was fine, i thinks its something with demo.

why dont you just buy the full version of the game? Im sure it has to be the demo if thats the only thing causing problems
